April and alex are saving money to buy new phones. each friend starts with some money and saves a specific amount each week. alex wrote an equation to show the total, y, she has saved at the end of each week, x. y = 20x + 125april made a graph to show the total he has saved at the end of each week. (graph as shown)compare the amount that each friend has when both friends start saving. select the correct answer from the answers below to complete the statement. alex starts a. 1b. 20c. 25d. 100e. 125 april starts f. 1g. 20h. 25i. 100j. 125 answer asap

Ascientist is tracking an object orbiting the sun that is found between mars and jupiter. in order to classify the object as an asteroid, it must be at least

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.
